摘　　要：主要描述了用Powerbuilder开发工具创建试题库以及设计应用程序界面。数据库采用的是PB自带的ASA本地数据库。数据库和应用程序的连接是通过ODBC连接起来的。界面设计力求界面完美、功能齐全。数据窗口的引进是本应用程序的一大特色。它的引进简化了程序。利用数据窗口 ,可以直接操作数据库中的数据 ,能够以图形化的方式增加、删除、修改 ,更新、查询数据 ,还可以指定数据的输入格式。试题内容、分析和答案字段的显示采用OLE对象来显示。OLE对象是专门用来显示大文本的控件。采用该对象解决了试题中同时显示文字、公式和图片的难点。整个应用程序是使用PB8.0自带PowerScript语言和SQL结构化查询语言来进行编的。This thesis mostly describes the problem ,that is ,to set up test questions warehouse and to design the interface of applied procedure. It adopts the database from the native database of Powerbuilder8.0. When you design the interface,database package will display the fields of subject number?circuit type and difficulty level.It presents us a direct and lovely interface.Introduction of database package is a characteristic of this applied procedure.This application simplifies the applied procedure .The user can operate the data which are stored in the warehouse directly. It includes so many functions which consist of addition ?deletion?modification?updating and query.It can also appoint the data' format.We adopt OLE object to display contents, analysis and answer. The OLE object uses exclusively in large text. Adopting that object solved a difficult problem which is to display words?formula and pictrures .In this applied procedure ,the whole program uses language of PowerScript and language of SQL to programme.
